Abstract
Equipment for analyzing a fluid selected from a hydrocarbon fluid, a refinery feedstock, a refinery intermediate, a product of a refinery process, or a component or reaction product thereof, having a portable apparatus containing at least two different analytical devices, each device being able to analyze the fluid. A sample plate is provided in association with the portable apparatus which has a receiver for a fluid to be analyzed, at least two fluidic channels, at least one sensor capable of responding to a physical or chemical property of the fluid, and/or at least one sample cell, and at least one additional fluidic channel for transferring a portion of the fluid or a component or reaction product thereof from the receiver to the at least one sensor and/or sample cell.
Claims22
An equipment set for analysing a fluid selected from a a refinery feedstock, a refinery intermediate and a product of a refinery process, or a component or reaction product thereof, which comprises
- a portable apparatus containing at least two different analytical devices, wherein said at least two different analytical devices include:
- (a) a first analytical device for determination of the boiling point profile of a refinery feedstock, a refinery intermediate or a product of a refinery process, and
- (b) at least one further analytical device associated with a database and an algorithm and capable of measuring at least one physical or chemical property of a refinery feedstock or a product of a refinery process, said equipment set being capable of determining at least the boiling point profile, the total acid number (TAN) and the density of a refinery feedstock or said product of a refinery process;
- wherein said first analytical device and said at least one further analytical device are each selected from a micro-distillation device, a micro-near infrared (NIR) spectrometer, a micro-oscillator device and a micro-gas chromatograph (GC);
- and
- a sample plate in association with said portable apparatus, which sample plate comprises (i) a receiver for a fluid to be analysed;
- (ii) at least two fluidic channels each adapted to transfer a portion of said fluid or a component or reaction product thereof from said receiver to one of said analytical devices contained in said portable apparatus;
- (iii) at least one of:
- at least one sensor capable of responding to a physical or chemical property of said fluid or a component or reaction product thereof, and at least one sample cell for containing a sample of said fluid or a component or reaction product thereof for spectroscopic or optical analysis;
- and (iv) at least one additional fluidic channel adapted to transfer a portion of said fluid or a component or reaction product thereof from said receiver to said at least one of:
- at least one sensor and at least one sample cell.
